WildBillKelsoe Posted April 4, 2015 Share Posted April 4, 2015 According to the manual: "The Sapphire’s antennae can’t be manually moved up-down or left- right like in modern fighters. Instead, it will scan ±30° in azimuth, and -1.5° and +17° in elevation, searching for any targets at a maximum of 30 km distance." For azimuth ok, I get it total 60°, 30° to each side. But for elevation, if I put a target at 30 km flying at 104000 meters (!!!!), does that mean I will detect it (even briefly, say its a helicopter in hover)? This means that in a right angled triangle apex at nose , the altitude difference is tan (17) x 30 km = 104 km, and this is pretty weird. Or I could be wrong. AWAITING ED NEW DAMAGE MODEL IMPLEMENTATION FOR WW2 BIRDS Fat T is above, thin T is below. Long T is faster, Short T is slower. Open triangle is AWACS, closed triangle is your own sensors. Double dash is friendly, Single dash is enemy. Circle is friendly. Strobe is jammer. Strobe to dash is under 35 km. HDD is 7 times range key. Radar to 160 km, IRST to 10 km. Stay low, but never slow.

xxJohnxx Posted April 4, 2015 Share Posted April 4, 2015 This means that in a right angled triangle apex at nose , the altitude difference is tan (17) x 30 km = 104 km, and this is pretty weird. Or I could be wrong. No, the tangent of 17° is 0.305. 0.305 multiplied by 30km is 9.17km.

WildBillKelsoe Posted April 4, 2015 Author Share Posted April 4, 2015 So its not an exact right angled triangle. Thanks John.

xxJohnxx Posted April 5, 2015 Share Posted April 5, 2015 (edited) So its not an exact right angled triangle. Yeah, the radar scan zone looks somewhat like that: Note: Excuse my paint skills! Too late to bother booting up Photoshop... Basically the red shaded area is the theoretical scan zone. The blue part resembles a zone that mathematically is further than 30km away from the radar, and therefore outside the radar range. The orange arrow would be the highest point with 9,17km, however that would be outside of the scan zone. I guess it probably would come down to about 8,5km to be within the scan zone. But all that is theoretically speaking. Given how vintage the radar is, I don't think my simple mathematics and drawings will apply. :D EDIT: Angle in the drawing should be 17° not 30°.

sissypilot Posted April 5, 2015 Share Posted April 5, 2015 You sad it right John but draw the triangle with 30 degrees instead of 17 :) Link to comment Share on other sites More sharing options...
xxJohnxx Posted April 5, 2015 Share Posted April 5, 2015 You sad it right John but draw the triangle with 30 degrees instead of 17 :) Oh, yeah, I confused that.

Elefant1301 Posted April 6, 2015 Share Posted April 6, 2015 Wouldn't the use of sinus be more interesting ? Sorry for the drawing, I used xxjohnxx's and modified it with an iPad... 1 Link to comment Share on other sites More sharing options...

HerVirek Posted June 23, 2015 Share Posted June 23, 2015 DEar all.. I trying to use and practice with Mig 21 radar.. And one Qeustion 30 km range are real?? Cause i do some practice missions with labels.. and never detect another aircraft more taht 7-9 Nm away B-52 -- 7NM F-5 6 NM C-130 8 Nm.. I warmed the radar, and follow the correct steps.. It´s a Bug? it´s normal work? It´s pilot error? Thanks in advance Link to comment Share on other sites More sharing options...
WildBillKelsoe Posted June 23, 2015 Author Share Posted June 23, 2015 I think LN waiting for ED to implement W2.0 then we'll see a plethora of improvements. I think target aspect angle also plays part. If the target AOT is 90 degrees (crossing left to right) it is more difficult than a pure pursuit target.
